 A. must yield the same value B. must yield different values C. may or may not yield the same value D. none of these Answer Report Discuss Option: C Explanation : If y = 11, the expression 3 * (y - 8) / 9 becomes 3 * 3 / 9. which evaluates to 1. But the expression ( y - 8 )/ 9 * 3 becomes 3 / 9 * 3. which evaluates to 0 (since 3 / 9 is 0) Click on Discuss to view users comments. prakash said: (7:38pm on Tuesday 30th April 2013) =[3*(y-8)] / 9=[3*(11-8)] / 9=[3*(3)] / 9=9 / 9/=12ed=[(y-8)/9] * 3=[(11-8)/9] * 3=[(3)/9] * 3=[1/3] * 3=1thus,both r samemeans ans. is A Write your comments here:

The following code fragment
int x, y =2, z, a;
x = ( y* = 2 ) + ( z = a = y )
printf ( "%d" , x );

 A. prints 8 B. prints 6 C. prints 6 or 8 depending on the compiler implementation D. is syntactically wrong Answer Report Discuss Option: C Explanation :  y * = 2 means y = y * 2  i.e. y = 4, in this problem. So. the expression is equivalent to x = 4 + 4, which is 8. So, 8 will be printed. However, the order in which the operands are evaluated is implementation-dependent. If the right operand is evaluated first, the result will be 6.  Click on Discuss to view users comments. Write your comments here:
